Input signal code (Setting range: 0 to 16)

[Description]

• This parameter is used for selecting input signals. Input signal varies depending on the sensors (2 types below). Set a code that corresponds to the sensor you use.

Type I : Thermocouples (9 kinds of signals)

Resistance bulbs (1 kind of signal)

Type II : Voltage, current

• Input signals can be selected within the same type. It is impossible to select input signals of a different type.

•For type II, to change from the voltage input to the current input, connect the supplied resistance of 250Ω be- tween terminals !7 and !8 (in the case of PXR4), and between terminals #5 and #6 (in the case of PXR5/9), in addition to changing the code. When changing from the current input to the voltage input, remove the resistance of 250 Ω as well as changing the code.

1. Power-on start: The ramp-soak operation starts to run from the current PV value.

2. Output at END: The output status at the END of the ramp-soak operation.

3. Output at OFF: The output status while the ramp-soak operation is set to OFF.

Repeat operation:

This function makes the ramp-soak operation to continue after one cycle of ramp-soak operation is completed. At the e vent of Repeat operation: OFF, the SV that is set in the final cycle is kept.

* Standby mode: Output: control output OFF or -3%

Alarm: OFF Control: OFF

Specifying control action, and output direction at input burn-out (Setting range: 0 to 19)

[Description]

• This parameter specifies action (Single/Dual and Heating/ Cooling), and output direction at input burn-out.

• The standard model (single output) or the heating/cooling control output (dual output) are available.

•There is defference of hardware between the standard model and the heating/cooling control output model. Set the code that is applicable to your controller.

• In general, reverse action is applyed for the heating process and direct action is applyed for the cooling process.

* “burn-out output” means the output direction

at input burn-out.

* The lower limit of a burn-out output indicates

that output is set to OFF, or 4mA or less. The upper limit indicates that output is set to ON, or 20mA or more.

The time of ON-delay alarm or timer function

[Description]

ON-delay alarm

•With this function, the alarm relay is closed after the predetermined delay time. (See operation q shown in the figure below.)

• In case the cause of the alarm is solved within the delay time, the alarm relay is not closed. (See operation e shown in the figure below.)

•The alarm relay is opened regardless of this parameter. (See operation w shown in the figure below.)

(Setting range: 0 to 9999 seconds)

•The timer display function shows the remaining time of timers 1, 2 and 3.

•The set time is counted down while the ON or OFF timer is activated.

•

While the ON timer is activated, the alarm relay is closed when the remaining time is 0. While the OFF timer is activated, the alarm relay is opened when the remaining time is 0.

• In case the alarm is set to OFF during standby, the ONdelay operation performs again when returning to RUN.

•When the delay time is changed during ON-delay operation, the alarm is activated in the changed delay time.

Timer function

•When the ON-delay timer is selected (ALMn = 32), the relay is closed in the set time after DI input is set to ON. While the DI input stays OFF, the timer cannot be activ ated.

• When the OFF-delay timer is selected (ALMn = 33), the timer cannot be activated while the DI input is set to ON. The relay is closed in the set time after DI input is set to OFF.

• How to set the point at which the alarm is actevated:

• Set the output of the PXR to ON continuously to provide the current to the heater.

•You can monitor the current value of the heater in the parameter of . Set the v alue that is 70 to 80 % of the monitored current value as the final set value.

•When the number of heaters is “n” (more than two), set the middle value between the current of “n” heaters and the current of (“n”-1) heaters.

• When the thyristor (SCR) phase control system is used to control the heater, the parameters of and cannot be used.

• In case detection of an error becomes difficult due to insufficient heater capacity, pass the wire through the CT twice to double the apparent current. This will improve the sensitivity of the CT. (In this case, set the value that is twice as much as the original value.)

• When winding the wire around the CT several times, be sure to wind in the same direction.

[Note]

To detect heater current, control output 1 must be kept on for 0.5 second or longer.

MV Output value

•When the value of retransmission output (example: SV) becomes equal to the set value of Ao-L, the retransmission output becomes 0% (output).

•When the value of retransmission output (example: PV) becomes equal to the set value of Ao-H, the retransmission output becomes 100% (output).

Note 1: Calculate the set value by using the following for-

mula (refer also to the setting example shown below).

Set value (%) = (A ÷ B) × 100 [%]

A = Temperature to be set – Set value of parameter “P-SL” B = Set value of parameter “P-SU” – Set value of “P-SL”

[Setting example] At K thermocouple input of 0 to 400˚C, make the setting so that the PV (value of

retransmission output type) becomes 0% at 100˚C, and 100% at 300˚C .

Since the measurement range is 0 to 400˚C, P – SL = 0 (lower limit v alue of measurement range), and P – SU = 400 (upper limit value of measurement range). So, from the formula shown above, A = (100˚C – 0) or (300˚C – 0), B = 400 – 0 = 400

1) Setting Ao-L : What position is 100˚C in the temperature range from 0 to 400˚C ? = 25% (=(100

Safety Precaution

● Before using the PXR, read the “Instruction Manual” or consult with your local distributor or Fuji Electric for safety

purpose.

● The uses and places for some of equipment described in this manual are limited. Some devices need regular inspec-

tions. Consult with your local distributor or Fuji Electric.

● Only electricians should connect this equipment.

● The contents of this manual have been prepared carefully. However, it should be noted that Fuji Electric is not respon-

sible for any loss, including consequential damage from errors in writing or missing information. Before operating the PXR, carefully read the safety precaution in the “Instruction Manual”.

Over-temperature Protection

Any control system design should take into account that any part of the system has the potential to fail.

For temperature control systems, continued heating should be considered the most dangerous condition, and the machine should be designed to automatically stop heating if unregulated due to the failure of the control unit or for any other reason.

The following are the most likely causes of unwanted continued heating:

1) Controller failure with heating output constantly on

2) Disengagement of the temperature sensor from the system

3) A short circuit in the thermocouple wiring

4) A valve or switch contact point outside the system is locked to keep the heat switched on.

In any application where physical injury or destruction of equipment might occur, we recommend the installation of independent safety equipment, with a separate temperature sensor, to disable the heating circuit in case of overheating.

The controller alarm signal is not designed to function as a protective measure in case of controller failure.
